Definitions
- the invention relates to a valve device, in particular for a washing area in the sanitary area, according to the preamble of patent claim 1.
- valve body can be transferred, for example via a lever linkage, from its position for releasing a flow (release position) through a connecting part attached to the washing area into its position for blocking such a flow (blocking position) and vice versa.
- the valve body is elongate and its lower section rests on a part of the lifting linkage that protrudes into the drain.
- This portion of the lift rod is typically located in a vertical pipeline below the fitting which connects the fitting to a downstream siphon.
- the lifting linkage also includes a part which is guided, for example, to a mixer tap at the washing area and which can be moved up and down manually in order to convert the valve body into its release position or blocked position.
- valve device has a relatively complicated structure.
- practice shows that such devices become dirty relatively quickly and have to be cleaned regularly and in a laborious manner.
- valve devices are, for example, from U.S. 6,363,544 B1 , U.S. 5,819,328 A such as DE 2 036 586 A1 known.
- Generic valve devices are, for example, in U.S. 3,849,809 as well as in the WO 2014/138783 A1 described.
- the object of the invention is to provide a valve device that is simpler in construction and easier to handle, and in particular is less prone to contamination.
- the valve device has a connection part with which it is usually attached to a drain of the washing area.
- the valve device also has a valve body which is designed to enable or block a flow through the connection part.
- the connection part is set up, for example, as a drain part.
- the connection part has a fixed device, by means of which the valve body is held in its position for releasing the flow (release position).
- the invention is therefore based on the idea of completely dispensing with the movable lifting linkage mentioned above in relation to the prior art. On the one hand, this simplifies the construction and manufacture of the valve device and the washing area overall; on the other hand, the valve device according to the invention is easier to handle.
- connection part ultimately serves in the sense of a double effect not only to fasten the valve device to the washing area but also to hold the valve body in its release position by means of the fixed device.
- the fixed device is at least one projection provided on the connection part, with the valve body preferably protruding at least partially into the connection part, the connection part being tubular and the at least one projection being arranged on an inner wall of the connection part.
- the projection can preferably be provided in one piece and therefore with little effort on the connection part, which contributes to a simple construction of the valve device.
- such a projection narrows the cross section of the connecting part and thus the outlet cross section only slightly. As previously indicated, such a valve device is therefore less likely to become soiled than a conventional valve device.
- valve body in its release position, sits on the fixed device, preferably on the at least one projection.
- a seating of the valve body on a part of the connection part can be implemented in a relatively simple manner and thus inexpensively, as will be explained in more detail below.
- the connecting part and the valve body are connected to one another so that they can be moved relative to one another, the valve body according to the invention having at least one groove on its outer circumference for receiving the at least one projection, and the at least one groove preferably being designed and arranged in such a way that the valve body moves out of its position for blocking the flow (Locking position) can be converted into its release position and vice versa by means of a preferably counterclockwise rotational movement.
- a projection/groove arrangement therefore corresponds to a tongue/groove connection known from wood interior fittings, with the difference that the valve body is designed to be movable relative to the connection part when the at least one groove of the valve body moves along the at least one projection of the connection part emotional.
- Such at least one groove can be provided on the valve body with little effort.
- a rotational movement for transferring the valve body from its blocking to its release position can be accomplished in a structurally simple manner.
- the at least one groove has a first section for raising/lowering the valve body and a second section adjoining the first section, with which the valve body rests on the sits at least one projection and is thereby held in its release position.
- the at least one groove with its two sections serves on the one hand to transfer the valve body from its blocking to its release position and vice versa, on the other hand also to hold the valve body in its release position in the sense of a double effect.
- the valve body is advantageously raised/lowered by means of a manually executable rotary movement of the valve body.
- a rotary movement can be carried out quickly and with little effort, it requires no special instructions and can also be carried out easily and without problems by children and old people.
- the at least one projection has a rounded top and the second section of the at least one groove has a complementarily shaped underside.
- the rounding of the upper side of the at least one projection ensures that on the one hand it offers only a low flow resistance to the outflowing liquid, and on the other hand it ensures that hair, for example, does not get caught on the at least one projection but is transported further by the liquid in the direction of the siphon. As a result, the risk of contamination of the valve device according to the invention is further reduced.
- the valve body has an overflow valve which, when the valve body is in the closed position, moves automatically from its closed position, which seals the valve body, to its open position, which allows the liquid to drain off, and vice versa, when a maximum fill level of a liquid in the washing area is exceeded.
- the valve device according to the invention can also be used as a so-called overflow device, with no overflow devices, such as overflow openings and flow connections between each overflow opening and a drain, having to be provided at the washing area. This also reduces the manufacturing costs for the washing area.
- valve device according to the invention is therefore used in the sense of a double effect not only for releasing or blocking a drain for the washing area but also as an overflow device, so that a Overflowing of the washing area and thus flooding a bathroom, for example, is effectively prevented.
- the overflow valve can be transferred from its closed to its open position and vice versa by the forces acting on it from the hydrostatic pressure of the liquid column, buoyancy and weight.
- the level of the hydrostatic pressure in relation to the counteracting buoyancy is therefore the trigger for transferring the overflow valve from its closed to its open position or leaving it in its closed position. It follows from this that the liquid in the washing area monitors itself to a certain extent. If the hydrostatic pressure rises above a threshold value, this pushes the overflow valve against the buoyancy from its closed to its open position. As long as the hydrostatic pressure is below the threshold value, the overflow valve remains in its closed position. With the aid of the valve device having an overflow valve, the above-mentioned operating principle can be implemented very simply and therefore inexpensively.
- the overflow valve is advantageously in its closed position when the valve body is in the release position. It follows that the valve body is used to drain liquid in the washing area or to accumulate it, while the overflow valve is only used in the closed position of the valve body to allow the liquid to flow out of the washing area when a maximum liquid level in the washing area is exceeded is.
- the head of the overflow valve is in the form of a spherical segment and a sealing surface in the valve body, against which the head of the overflow valve bears in a sealing manner in its closed position, is correspondingly shaped, ring-shaped. This ultimately creates a sealing surface and not just a sealing line between the valve body and the overflow valve.
- the overflow valve is designed in the manner of a hollow cone and, in its open position, performs a wobbling movement due to the annular flow of the liquid running off.
- the hollow cone-like design of the overflow valve contributes to providing the necessary buoyancy forces, which hold the overflow valve in its closed position.
- the tumbling movement of the overflow valve brought about by the annular flow of the liquid has the result that dirt can settle less easily on the overflow valve and on the valve device as a whole, as a result of which the cleaning effort is reduced.
- This further development therefore also contributes to easier handling of the valve device according to the invention.
- valve device 1 A schematic, perspective, exploded view of a valve device 1, in particular for a washing area in the sanitary area, which is not shown in detail, is shown in 1 shown.
- the valve device 1 can therefore be used in particular, but not exclusively, in a washing area, such as a washbasin, a shower or a bathtub.
- the valve device is usually located at the outlet of the washing area, ie in the position where a liquid such as water caught by the washing place usually drains from the washing place.
- the valve device 1 has a connecting part 2, which is usually inserted from above into the drain (not shown) of the washstand (also not shown), detachably connected to a counterpart provided on the underside of the washstand and via the counterpart and a pipeline (not shown) to a not-shown one siphon is connected.
- the valve device 1 also has a valve body 3 which is designed to enable or block a flow through the connection part 2 .
- the connection part and the valve body also function as a drain part, with the help of which liquid can drain out of the washing area or be accumulated in it.
- the connecting part 2 has a stationary device 4, by means of which the valve body 3 can be held in its position for releasing the flow (release position).
- the stationary device 4 is usually connected to the connection part 2 in one piece. It is clear that the fixed device is therefore not movable, in contrast to the lifting linkage previously described in relation to the prior art.
- the fixed device 4 is at least one projection 5, 6, 7 provided on the connection part 2, with three projections 5 to 7, spaced evenly apart from one another, being provided according to the exemplary embodiment shown.
- the valve body 3 protrudes at least partially into the connection part 2 .
- the connection part 2 is tubular and the respective projection 5 to 7 is arranged on an inner wall 10 of the connection part 2 .
- Each projection 5 to 7 protrudes a little into the free cross section of the connection part 2 .
- valve body 3 sits in its in the 3 and 5 shown release position on the fixed device 4, preferably on the at least one projection 5 to 7 on.
- the valve body is usually seated on each projection 5 to 7 in its release position.
- the projections 5 to 7 are in the same horizontal plane arranged.
- Connection part 2 and valve body 3 are connected to one another so that they can be moved relative to one another, valve body 3 having at least one groove 12 on its outer circumference 11 for receiving at least one projection 5 to 7 .
- a groove 12 is usually provided for each projection 5, 6 and 7, a groove 12 is usually provided.
- the at least one groove 12 is located in that area of the valve body which protrudes into the connection part and is therefore arranged in all of its operating positions within the connection part.
- the at least one groove 12 is designed and arranged in such a way that the valve body 3 can be transferred from its position for blocking the flow (blocking position) into its release position and vice versa by means of a rotary movement preferably directed counterclockwise.
- the release position of the valve body and thus the valve device is in the 3 and 5 shown.
- the groove 12 has a first section 13 for raising/lowering the valve body 2 and a second section 14 adjoining the first section 13, with which the valve body 3 rests on the at least one projection 5 to 7 and is thus in its release position is held.
- the valve body 3 is raised/lowered by means of a manually executable rotary movement of the valve body, with the valve body being in its release position (see FIG 3 and 5 ) is in a raised position and in its blocking position in a lowered position, in which the valve body protrudes deeper into the connection part compared to the release position.
- the at least one projection 5 to 7 has a rounded top 15 and the second section 14 of the groove 12 has a complementarily shaped underside 16, so that the valve body 13 in the area of its rounded underside 16 of the second section 14 of the groove 12 on the rounded top each projection 5 to 7 can be seated.
- the sections 13 and 14 of the groove 12 are designed in such a way that the valve body is initially raised further and further when it is transferred from the blocking to the release position and, when the underside 16 of the groove 12 in question touches the top 15 of the respective projection 5 to 7 slides open completely, then lowers again a bit.
- the valve body 3 has an overflow valve 17.
- the valve body according to the invention can be used both in conventional washing areas having an overflow device, such as an overflow opening and an overflow line connecting this to a drain pipe, and in washing areas without such an overflow device.
- the overflow valve 17 automatically moves out of its closed position, which seals the valve body 3 , when a maximum filling level of a liquid in the washing area is exceeded, as shown in FIGS 3 and 5 shown, in the direction of arrow A (see figure 5 ) into its open position allowing the liquid to drain and vice versa.
- the overflow valve 17 In its open position, the overflow valve 17 has moved away from the valve body 3 and is spaced apart from it.
- the overflow valve can be transferred from its closed to its open position and vice versa by the forces acting on it from the hydrostatic pressure of the liquid column, buoyancy and weight.
- the connection part 2 is connected to a connection element 20, as shown in dashed lines in figure 5 is indicated.
- the connection element 20 can be part of a siphon not shown in detail.
- a liquid level 21 which is set up in such a way that the overflow valve is usually in its closed position due to the forces acting on it, in particular the buoyancy forces, as is the case in FIGS 3 and 5 is shown.
- a liquid 22 in which the overflow valve 17 is at least partially immersed to such an extent that the buoyancy forces act on the overflow valve 17 into its closed position, provided that there is no liquid column above the overflow valve 17 that is of such a nature that it could block the overflow valve transferred or pressed into its open position.
- the overflow valve is located as in figure 5 indicated (also) in the release position of the valve body 3 in its closed position. In the blocking position of the valve body, the overflow valve is in its closed position until the maximum filling level of the liquid in the washing area transfers the overflow valve from its closed to its open position due to the hydrostatic pressure.
- the valve body 3 has a circumferential sealing lip 23, which is moved away from the connection part 2 in the release position of the valve body 3, as is the case 3 and 5 show.
- the projections 5 to 6 are in the area of the upper ends of the first section 13 of the grooves 12.
- the valve body 3 has moved so far down, i.e. towards the connection part 2, that the sealing lip 23 rests sealingly on an inner edge 24 of the connection part 2 .
- valve body 3 above its sealing lip 23 has a central opening 25 above which a cover 27 is held via ribs 26 .
- the cover 27 is thus at a distance from the central opening 25 .
- the cover 27 and ribs 26 are connected to the valve body 3 in one piece.
- the overflow valve 17 has a head 30 which is formed like a spherical segment. Furthermore, a sealing surface 31 in the valve body 3, against which the head 30 of the overflow valve 17 bears in a sealing manner in its closed position, is correspondingly shaped, ring-shaped. According to a preferred embodiment, the overflow valve 17, as shown in FIGS 1 , 3 and 5 indicated, designed like a hollow cone. In its open position, in which the head 30 of the overflow valve has moved away from the sealing surface 31 of the valve body 3 in the direction of arrow A due to the hydrostatic pressure of the liquid accumulated in the washing area, the overflow valve 17 performs a wobbling movement.
- peripheral ribs 32 which are located on the head 30 of the overflow valve 17 below the spherical section-like surface of the head, as is shown in 1 is shown.
- the ribs 32 extend along or parallel to the longitudinal axis 33 of the valve device 1 and thus also of the valve body 3. In the side view, the peripheral ribs 32 continue the rounding of the spherical cutout-like part of the head 30, so that the overflow valve 17 is inside the valve body 3 can move in the manner of a ball joint.
- valve device With the valve device according to the invention, contamination in the drainage area of a washing area is avoided. Dirt parts can neither get caught nor lie on the device.
- the valve device is also suitable for so-called attachment washbasins that can be stowed away without an overflow opening.
- the valve device 1 has its overflow and drain functions separated from each other.
- the overflow valve 17 In the release position of the valve body 3, the overflow valve 17 is in its closed position due to the forces acting on it, in particular due to the buoyancy forces.
- the overflow valve 17 is used exclusively to prevent the washing area from overflowing.
- the valve body can easily be transferred from its release position to its blocking position and vice versa by a simple rotary movement.
- the projections 5 to 7 then slide along the sections 13 and 14 of the grooves 12, so that the projections 5 to 7 are either at the upper end of the first section 13 of the grooves 12 (blocking position of the valve body) or in the area of the second section 14 of the Grooves 12 (release position of the valve body) are located.

Description
Die Erfindung zieht sich auf eine Ventilvorrichtung, insbesondere für einen Waschplatz im Sanitärbereich, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a valve device, in particular for a washing area in the sanitary area, according to the preamble of
Eine derartige Ventilvorrichtung ist aus der Praxis bekannt. Bei dieser Ventilvorrichtung ist der Ventilkörper beispielsweise über ein Hebelgestänge aus seiner Stellung zum Freigeben eines Durchflusses (Freigabestellung) durch ein am Waschplatz befestigtes Anschlussteil in seine Stellung zum Sperren eines solchen Durchflusses (Sperrstellung) und umgekehrt überführbar. Dazu ist der Ventilkörper länglich ausgebildet und liegt mit seinem unteren Abschnitt auf einem in den Ablauf hineinragenden Teil des Hebegestänges auf. Dieser Teil des Hebegestänges befindet sich üblicherweise in einer vertikalen Rohrleitung unterhalb des Anschlussteils, welche das Anschlussteil mit einem nachgeordneten Siphon verbindet. Das Hebegestänge umfasst ferner einen beispielsweise zu einer Mischbatterie am Waschplatz geführten Teil, welcher manuell auf- und abbewegbar ist, um dadurch den Ventilkörper in seine Freigabestellung oder Sperrstellung zu überführen.Such a valve device is known from practice. In this valve device, the valve body can be transferred, for example via a lever linkage, from its position for releasing a flow (release position) through a connecting part attached to the washing area into its position for blocking such a flow (blocking position) and vice versa. For this purpose, the valve body is elongate and its lower section rests on a part of the lifting linkage that protrudes into the drain. This portion of the lift rod is typically located in a vertical pipeline below the fitting which connects the fitting to a downstream siphon. The lifting linkage also includes a part which is guided, for example, to a mixer tap at the washing area and which can be moved up and down manually in order to convert the valve body into its release position or blocked position.
Eine solche Ventilvorrichtung ist einerseits relativ kompliziert aufgebaut. Andererseits zeigt die Praxis, dass derartige Vorrichtungen relativ schnell verschmutzen und regelmäßig aufwändig gereinigt werden müssen.On the one hand, such a valve device has a relatively complicated structure. On the other hand, practice shows that such devices become dirty relatively quickly and have to be cleaned regularly and in a laborious manner.
Herkömmliche Ventilvorrichtungen sind beispielsweise aus den
Der Erfindung liegt die Aufgabe zugrunde, eine Ventilvorrichtung zu schaffen, die einfacher aufgebaut und leichter handhabbar ist, insbesondere weniger leicht zu Verschmutzungen neigt.The object of the invention is to provide a valve device that is simpler in construction and easier to handle, and in particular is less prone to contamination.
Diese Aufgabe wird erfindungsgemäß durch eine Ventilvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.According to the invention, this object is achieved by a valve device having the features of
Wie zuvor beschrieben, hat die Ventilvorrichtung ein Anschlussteil, mit dem sie üblicherweise an einem Ablauf des Waschplatzes befestigt ist. Die Ventilvorrichtung hat ferner einen Ventilkörper, welcher zum Freigeben oder Sperren eines Durchflusses durch das Anschlussteil ausgebildet ist. Das Anschlussteil ist beispielsweise als Ablaufteil eingerichtet. Erfindungsgemäß weist das Anschlussteil eine feststehende Einrichtung auf, mittels der der Ventilkörper in seiner Stellung zum Freigeben des Durchflusses (Freigabestellung) gehalten ist. Der Erfindung liegt daher der Gedanke zugrunde, auf das zuvor in Bezug auf den Stand der Technik erwähnte bewegliche Hebegestänge vollständig zu verzichten. Dadurch wird zum einen Aufbau und Herstellung der Ventilvorrichtung und des Waschplatzes insgesamt vereinfacht; zum anderen ist die erfindungsgemäße Ventilvorrichtung leichter handhabbar. Dies ist darauf zurückzuführen, dass es bei letzterer wegen des Wegfalls eines quer in der Rohrleitung zum Siphon sitzenden Hebegestänges weniger leicht zu Verschmutzungen kommen kann, so dass der Reinigungsaufwand insgesamt deutlich verringert ist. Im Übrigen kann der Ventilkörper wegen des Wegfalls des Hebegestänges auch hinsichtlich seiner Baulänge deutlich kürzer ausgebildet sein, was dessen Handhabbarkeit und Reinigung ebenfalls erleichtert und zu geringeren Herstellungskosten führt. Insofern dient das Anschlussteil im Sinne einer Doppelwirkung letztlich nicht nur zur Befestigung der Ventilvorrichtung am Waschplatz sondern auch dazu, den Ventilkörper mittels der feststehenden Einrichtung in seiner Freigabestellung zu halten.As described above, the valve device has a connection part with which it is usually attached to a drain of the washing area. The valve device also has a valve body which is designed to enable or block a flow through the connection part. The connection part is set up, for example, as a drain part. According to the invention, the connection part has a fixed device, by means of which the valve body is held in its position for releasing the flow (release position). The invention is therefore based on the idea of completely dispensing with the movable lifting linkage mentioned above in relation to the prior art. On the one hand, this simplifies the construction and manufacture of the valve device and the washing area overall; on the other hand, the valve device according to the invention is easier to handle. This is due to the fact that in the case of the latter, since there is no lifting linkage sitting transversely in the pipeline to the siphon, contamination can occur less easily, so that the overall cleaning effort is significantly reduced. In addition, the valve body can also be made significantly shorter in terms of its overall length due to the omission of the lifting linkage, which also makes it easier to handle and clean and leads to lower production costs. In this respect, the connection part ultimately serves in the sense of a double effect not only to fasten the valve device to the washing area but also to hold the valve body in its release position by means of the fixed device.
Die feststehende Einrichtung ist wenigstens ein am Anschlussteil vorgesehener Vorsprung, wobei vorzugsweise der Ventilkörper zumindest teilweise in das Anschlussteil hineinragt, das Anschlussteil rohrförmig ist und der wenigstens eine Vorsprung an einer Innenwand des Anschlussteils angeordnet ist. Ein solcher Vorsprung kann vorzugsweise einstückig und daher mit geringem Aufwand am Anschlussteil vorgesehen werden, was mit zu einem einfachen Aufbau der Ventilvorrichtung beiträgt. Anders als beim Hebelgestänge, bei dem ein Teil den Querschnitt einer nachfolgenden Rohrleitung nahezu vollständig durchdringt, verengt ein solcher Vorsprung den Querschnitt des Anschlussteils und damit den Ablaufquerschnitt nur geringfügig. Wie zuvor bereits angedeutet verschmutzt eine derartige Ventilvorrichtung daher weniger leicht als eine herkömmliche Ventilvorrichtung.The fixed device is at least one projection provided on the connection part, with the valve body preferably protruding at least partially into the connection part, the connection part being tubular and the at least one projection being arranged on an inner wall of the connection part. Such a The projection can preferably be provided in one piece and therefore with little effort on the connection part, which contributes to a simple construction of the valve device. In contrast to the lever linkage, in which one part almost completely penetrates the cross section of a subsequent pipeline, such a projection narrows the cross section of the connecting part and thus the outlet cross section only slightly. As previously indicated, such a valve device is therefore less likely to become soiled than a conventional valve device.
Gemäß einer anderen Weiterbildung sitzt der Ventilkörper in seiner Freigabestellung auf der feststehenden Einrichtung, vorzugsweise auf dem wenigstens einen Vorsprung, auf. Ein derartiges Aufsitzen des Ventilkörpers auf einem Teil des Anschlussteils lässt sich auf relativ einfache Art und Weise und damit preiswert realisieren, wie nachfolgend näher erläutert wird.According to another development, in its release position, the valve body sits on the fixed device, preferably on the at least one projection. Such a seating of the valve body on a part of the connection part can be implemented in a relatively simple manner and thus inexpensively, as will be explained in more detail below.
Anschlussteil und Ventilkörper sind relativ zueinander bewegbar miteinander verbunden, wobei der Ventilkörper erfindungsgemäß an seinem Außenumfang wenigstens eine Nut zum Aufnehmen des wenigstens einen Vorsprungs hat und wobei vorzugsweise die wenigstens eine Nut derart ausgebildet und angeordnet ist, dass der Ventilkörper aus seiner Stellung zum Sperren des Durchflusses (Sperrstellung) mittels einer vorzugsweise gegen den Uhrzeigersinn gerichteten Drehbewegung in seine Freigabestellung und umgekehrt überführbar ist. Eine solche Vorsprung/Nut-Anordnung entspricht daher einer aus dem Holz-Innenausbau bekannten Feder/Nut-Verbindung mit dem Unterschied, dass der Ventilkörper relativ zum Anschlussteil bewegbar ausgebildet ist, wenn sich die wenigstens eine Nut des Ventilkörpers entlang dem wenigstens einen Vorsprung des Anschlussteils bewegt. Eine solche wenigstens eine Nut kann mit geringem Aufwand am Ventilkörper vorgesehen werden. Ferner kann eine Drehbewegung zum Überführen des Ventilkörpers aus seiner Sperr- in seine Freigabestellung konstruktiv einfach bewerkstelligt werden.The connecting part and the valve body are connected to one another so that they can be moved relative to one another, the valve body according to the invention having at least one groove on its outer circumference for receiving the at least one projection, and the at least one groove preferably being designed and arranged in such a way that the valve body moves out of its position for blocking the flow (Locking position) can be converted into its release position and vice versa by means of a preferably counterclockwise rotational movement. Such a projection/groove arrangement therefore corresponds to a tongue/groove connection known from wood interior fittings, with the difference that the valve body is designed to be movable relative to the connection part when the at least one groove of the valve body moves along the at least one projection of the connection part emotional. Such at least one groove can be provided on the valve body with little effort. Furthermore, a rotational movement for transferring the valve body from its blocking to its release position can be accomplished in a structurally simple manner.
Gemäß einer bevorzugten Weiterbildung weist die wenigstens eine Nut einen ersten Abschnitt zum Anheben/Absenken des Ventilkörpers und einen zweiten, sich an den ersten Abschnitt anschließenden Abschnitt auf, mit dem der Ventilkörper auf dem wenigstens einen Vorsprung aufsitzt und dadurch in seiner Freigabestellung gehalten ist. Insofern dient die wenigstens eine Nut mit ihren beiden Abschnitten einerseits zum Überführen des Ventilkörpers aus dessen Sperr- in dessen Freigabestellung und umgekehrt, andererseits im Sinne einer Doppelwirkung auch zum Halten des Ventilkörpers in dessen Freigabestellung.According to a preferred development, the at least one groove has a first section for raising/lowering the valve body and a second section adjoining the first section, with which the valve body rests on the sits at least one projection and is thereby held in its release position. In this respect, the at least one groove with its two sections serves on the one hand to transfer the valve body from its blocking to its release position and vice versa, on the other hand also to hold the valve body in its release position in the sense of a double effect.
Vorteilhafterweise erfolgt das Anheben/Absenken des Ventilkörpers mittels einer manuell ausführbaren Drehbewegung des Ventilkörpers. Eine solche Drehbewegung ist schnell und mit geringem Aufwand durchführbar, sie erfordert keine besondere Anleitung und kann auch von Kindern und alten Menschen leicht und unproblematisch ausgeführt werden.The valve body is advantageously raised/lowered by means of a manually executable rotary movement of the valve body. Such a rotary movement can be carried out quickly and with little effort, it requires no special instructions and can also be carried out easily and without problems by children and old people.
Gemäß einer anderen bevorzugten Weiterbildung weist der wenigstens eine Vorsprung eine abgerundete Oberseite und der zweite Abschnitt der wenigstens einen Nut eine komplementär geformte Unterseite auf. Durch die Abrundung der Oberseite des wenigstens einen Vorsprungs ist sichergestellt, dass dieser einerseits der abfließenden Flüssigkeit nur einen geringen Strömungswiderstand entgegensetzt, andererseits ist gewährleistet, dass beispielsweise Haare an dem wenigstens einen Vorsprung nicht hängenbleiben sondern von der Flüssigkeit weiter in Richtung Siphon transportiert werden. Dadurch ist die Verschmutzungsgefahr der erfindungsgemäßen Ventilvorrichtung weiter verringert.According to another preferred development, the at least one projection has a rounded top and the second section of the at least one groove has a complementarily shaped underside. The rounding of the upper side of the at least one projection ensures that on the one hand it offers only a low flow resistance to the outflowing liquid, and on the other hand it ensures that hair, for example, does not get caught on the at least one projection but is transported further by the liquid in the direction of the siphon. As a result, the risk of contamination of the valve device according to the invention is further reduced.
Gemäß einer besonders bevorzugten Weiterbildung weist der Ventilkörper ein Überlaufventil auf, das in der Sperrstellung des Ventilkörpers bei Überschreiten einer maximalen Füllstandshöhe einer Flüssigkeit im Waschplatz selbsttätig aus seiner den Ventilkörper abdichtenden Schließstellung in seine ein Ablaufen der Flüssigkeit gestattenden Öffnungsstellung und umgekehrt verfährt. Insofern kann die erfindungsgemäße Ventilvorrichtung auch als sogenannte Überlaufvorrichtung eingesetzt werden, wobei am Waschplatz keinerlei Überlaufeinrichtungen, wie zum Beispiel Überlauföffnungen und Strömungsverbindungen zwischen jeder Überlauföffnung und einem Abfluss vorzusehen sind. Damit verringert sich auch der Herstellungsaufwand für den Waschplatz. Die erfindungsgemäße Ventilvorrichtung dient also im Sinne einer Doppelwirkung nicht nur zum Freigeben oder Sperren eines Ablaufs für den Waschplatz sondern auch als Überlaufvorrichtung, so dass ein Überlaufen des Waschplatzes und damit ein Überschwemmen beispielsweise eines Badezimmers wirksam verhindert ist.According to a particularly preferred development, the valve body has an overflow valve which, when the valve body is in the closed position, moves automatically from its closed position, which seals the valve body, to its open position, which allows the liquid to drain off, and vice versa, when a maximum fill level of a liquid in the washing area is exceeded. In this respect, the valve device according to the invention can also be used as a so-called overflow device, with no overflow devices, such as overflow openings and flow connections between each overflow opening and a drain, having to be provided at the washing area. This also reduces the manufacturing costs for the washing area. The valve device according to the invention is therefore used in the sense of a double effect not only for releasing or blocking a drain for the washing area but also as an overflow device, so that a Overflowing of the washing area and thus flooding a bathroom, for example, is effectively prevented.
Gemäß einer anderen bevorzugten Weiterbildung ist das Überlaufventil durch die an ihm angreifenden Kräfte aus hydrostatischem Druck der Flüssigkeitssäule, Auftrieb und Gewicht aus seiner Schließ- in seine Öffnungsstellung und umgekehrt überführbar. Die Höhe des hydrostatischen Drucks im Verhältnis zu dem diesem entgegen wirkenden Auftrieb ist also der Auslöser dafür, das Überlaufventil aus seiner Schließ- in seine Öffnungsstellung zu überführen oder in seiner Schließstellung zu belassen. Daraus folgt, dass sich die im Waschplatz befindliche Flüssigkeit gewissermaßen selbst überwacht. Steigt der hydrostatische Druck über einen Schwellenwert an, drückt dieser das Überlaufventil gegen den Auftrieb aus dessen Schließ- in dessen Öffnungsstellung. Solange der hydrostatische Druck unterhalb des Schwellenwertes liegt, verharrt das Überlaufventil in seiner Schließstellung. Mithilfe der ein Überlaufventil aufweisenden Ventilvorrichtung ist das vorgenannte Wirkprinzip sehr einfach und damit kostengünstig realisierbar.According to another preferred development, the overflow valve can be transferred from its closed to its open position and vice versa by the forces acting on it from the hydrostatic pressure of the liquid column, buoyancy and weight. The level of the hydrostatic pressure in relation to the counteracting buoyancy is therefore the trigger for transferring the overflow valve from its closed to its open position or leaving it in its closed position. It follows from this that the liquid in the washing area monitors itself to a certain extent. If the hydrostatic pressure rises above a threshold value, this pushes the overflow valve against the buoyancy from its closed to its open position. As long as the hydrostatic pressure is below the threshold value, the overflow valve remains in its closed position. With the aid of the valve device having an overflow valve, the above-mentioned operating principle can be implemented very simply and therefore inexpensively.
Vorteilhafterweise befindet sich das Überlaufventil in der Freigabestellung des Ventilkörpers in seiner Schließstellung. Daraus folgt, dass der Ventilkörper dazu dient, Flüssigkeit im Waschplatz ablaufen oder diese aufstauen zu lassen, während das Überlaufventil nur in der Sperrstellung des Ventilkörpers dazu dient, ein Abfließen der Flüssigkeit aus dem Waschplatz zu ermöglichen, wenn eine maximale Füllstandshöhe der Flüssigkeit im Waschplatz überschritten ist.The overflow valve is advantageously in its closed position when the valve body is in the release position. It follows that the valve body is used to drain liquid in the washing area or to accumulate it, while the overflow valve is only used in the closed position of the valve body to allow the liquid to flow out of the washing area when a maximum liquid level in the washing area is exceeded is.
Gemäß einer anderen Weiterbildung ist der Kopf des Überlaufventils kugelausschnittartig und eine Dichtfläche im Ventilkörper, an der der Kopf des Überlaufventils in dessen Schließstellung abdichtend anliegt, entsprechend geformt, ringförmig ausgebildet. Damit ist letztlich eine Dichtfläche und nicht nur eine Dichtlinie zwischen dem Ventilkörper und dem Überlaufventil realisiert.According to another development, the head of the overflow valve is in the form of a spherical segment and a sealing surface in the valve body, against which the head of the overflow valve bears in a sealing manner in its closed position, is correspondingly shaped, ring-shaped. This ultimately creates a sealing surface and not just a sealing line between the valve body and the overflow valve.
Gemäß einer bevorzugten Weiterbildung ist das Überlaufventil hohlkegelartig ausgebildet und führt in seiner Öffnungsstellung durch die Ringströmung der ablaufenden Flüssigkeit eine Taumelbewegung aus. Die hohlkegelartige Ausbildung des Überlaufventils trägt mit dazu bei, die nötigen Auftriebskräfte bereitzustellen, welche das Überlaufventil in seiner Schließstellung halten. Die durch die Ringströmung der Flüssigkeit herbeigeführte Taumelbewegung des Überlaufventils hat zur Folge, dass sich Schmutz weniger leicht am Überlaufventil und an der Ventilvorrichtung insgesamt absetzen kann, wodurch sich der Reinigungsaufwand verringert. Auch diese Weiterbildung trägt daher zur leichteren Handhabbarkeit der erfindungsgemäßen Ventilvorrichtung bei.According to a preferred development, the overflow valve is designed in the manner of a hollow cone and, in its open position, performs a wobbling movement due to the annular flow of the liquid running off. The hollow cone-like design of the overflow valve contributes to providing the necessary buoyancy forces, which hold the overflow valve in its closed position. The tumbling movement of the overflow valve brought about by the annular flow of the liquid has the result that dirt can settle less easily on the overflow valve and on the valve device as a whole, as a result of which the cleaning effort is reduced. This further development therefore also contributes to easier handling of the valve device according to the invention.

Ferner ist eine Dichtfläche 31 im Ventilkörper 3, an der der Kopf 30 des Überlaufventils 17 in dessen Schließstellung abdichtend anliegt, entsprechend geformt, ringförmig ausgebildet. Gemäß einer bevorzugten Ausführungsform ist das Überlaufventil 17, wie in den
Mit der erfindungsgemäßen Ventilvorrichtung werden Verschmutzungen im Ablaufbereich eines Waschplatzes vermieden. Schmutzteile können an der Vorrichtung weder hängen- noch liegenbleiben. Die Ventilvorrichtung ist auch für sogenannte Ansatzwaschbecken geeignet, die ohne Überlauföffnung staubar sind. Gemäß vorstehender Beschreibung sind bei der Ventilvorrichtung 1 Überlauf- und Ablauffunktion voneinander getrennt. In der Freigabestellung des Ventilkörpers 3 befindet sich das Überlaufventil 17 aufgrund der an ihm angreifenden Kräfte, insbesondere aufgrund der Auftriebskräfte, in seiner Schließstellung. Das Überlaufventil 17 dient ausschließlich dazu, ein Überlaufen des Waschplatzes zu verhindern. Der kugelausschnittartig gestaltete Kopf 30 des Überlaufventils 17 dichtet in allen Stellungen des Überlaufventils ab, solange sich das Überlaufventil in seiner Schließstellung befindet. Durch eine einfache Drehbewegung kann der Ventilkörper leicht aus seiner Freigabe- in seine Sperrstellung und umgekehrt überführt werden. Die Vorsprünge 5 bis 7 gleiten dann entlang der Abschnitte 13 bzw. 14 der Nuten 12, so dass sich die Vorsprünge 5 bis 7 entweder am oberen Ende des ersten Abschnitts 13 der Nuten 12 (Sperrstellung des Ventilkörpers) oder im Bereich des zweiten Abschnitts 14 der Nuten 12 (Freigabestellung des Ventilkörpers) befinden. Wie zuvor erwähnt sitzt der Ventilkörper 3 in seiner Freigabestellung mit seinen zweiten Abschnitten 14 der Nuten 12 auf den abgerundeten Oberseiten 15 der Vorsprünge 5 bis 7 auf.With the valve device according to the invention, contamination in the drainage area of a washing area is avoided. Dirt parts can neither get caught nor lie on the device. The valve device is also suitable for so-called attachment washbasins that can be stowed away without an overflow opening. As described above, the
Damit ist eine Ventilvorrichtung geschaffen, die einfach aufgebaut und leicht handhabbar ist, insbesondere weniger leicht zu Verschmutzungen neigt.This creates a valve device that is simple in construction and easy to handle, and in particular is less prone to contamination.
